This could take a while, so I'll simply put the answer with the theorem I used to figure it out with.

1) 45° - minor arc; Central Angles/Arcs Theorem

2) 180° - semi circle; Diameter Theorem? (Whichever theorem states that the diameter separates a circle into two 180° semi circles)

3) 75° - minor arc; Angle Addition Postulate

4) 105° - minor arc; Angle Addition Postulate

5) 225° - major arc; Angle Addition Postulate

6) 45° - minor arc; Vertical Angles Theorem

7) 135° - minor arc; Angle Addition Postulate

8) 240° - major arc; Angle Addition Postulate

9) 315° - major arc; Angle Subtraction Postulate, i think? lol.

10) 180° - semi circle; Diameter Theorem or whatever it's called lol.

Additionally, I determined whether or not an angle was a major arc, minor arc, or semi circle with the knowledge that:

minor arc - less than 180 degrees
major arc - more than 180 degrees
semi circle - is 180 degrees.

Have a nice day, fam. Spread The Love. lol I'm tired after typing all this out :P

ILL MARK AS BRAINLIEST!! AND GIVE 10 POINTS!!! Are the following lines parallel, perpendicular, or neither?

Licemer1 [7]

Answer:

b perpendicular

Step-by-step explanation:

all that is needed to do is the Y2 - y1 / X2 - X1 formula and then compare the two slopes making sure they are inverse opposites

Line 1) -7 -8 / -3 -2 X= 3X

Line 2) -3 - 0 / 12 - 3 X = -1 / 3X

Because they are inverse opposites of each other they are perpendicular had they had the exact same slopes they would have been parallels.

Ariana is shipping 8 bags of granola to a customer. Each bag weighs 22 ounces and the maximum weight she can ship in one box is

Anuta_ua [19.1K]

Ariana cannot ship all the bags in one box.

Ariana will be sending 8 bags which will weigh a total of:

= 22 ounces x 8

= 176 ounces

You need to convert this to pounds to see if it will fit in the box:

1 pound = 16 ounces

176 ounces in pounds is therefore:

= 176 / 16

= 11 pounds

The box can only take 10 pounds and 5 ounces which is less than the 11 pounds the bags weigh.

Ariana cannot ship all the bags in one box.

One of the questions Rasmussen Reports included on a 2018 survey of 2,500 likely voters asked if the country is headed in right

kap26 [50]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

553 - No

70 - Not Sure

384 - Yes

Total = (553 + 70 + 384) = 1007

Proportion who do think country is headed in the right direction :

P = yes / total = 384/1007 = 0.381

b.) Error margin at 95%

Margin of Error = Zcritical * √p(1-p)/n

1-p = 1 - 0.381 = 0.619

Zcritical at 95% = 1.96

Margin of error = 1.96 * √0.381(0.619)/1007

Margin of error = 0.030

C.)

95% confidence interval for heading in the right direction:

P ± margin of error

P ± 0.030

Lower boundary = 0.381 - 0.030 = 0.351

Upper boundary = 0.381 + 0.030 = 0.411

(0.351 ; 0.411)

D.)

Confidence interval for people who don't think :

P = 553 / 1007 = 0.549

Confidence interval = P ± margin of error

Error margin at 95%

Margin of Error = Zcritical * √p(1-p)/n

1-p = 1 - 0.549 = 0.451

Zcritical at 95% = 1.96

Margin of error = 1.96 * √0.549(0.451)/1007

Margin of error = 0.031

P ± margin of error

P ± 0.031

Lower boundary = 0.549 - 0.031 = 0.518

Upper boundary = 0.549 + 0.031 = 0.580

(0.518 ; 0.580)

E.)

The interval with smaller error margin is ; 0.030 (those who think country is headed in the right direction because sample proportion is farther from .5 / farther from 1)
